题目链接:https://leetcode.com/problems/jump-game-ii/?tab=Description   给定一个数组,数组中的数值表示在当前位置能够向前跳动的最大距离.   求解出从下标为0开始到下标到数组最后一个所需要的最少跳动次数!   1.当数组为空或者数组长度等于1时,不需要跳动,因此返回0 否则初始化step=1 2.初始化left=0 right = nums[0] 当left<=right时进入循环体中.  3.从第i=0开始,如果当前跳动距离大于数组…

给定一个非负整数数组,你最初位于数组的首位.数组中的每个元素表示你在该位置的最大跳跃长度.你的目标是用最小跳跃次数到达最后一个索引.例如: 给定一个数组 A = [2,3,1,1,4]跳到最后一个索引的最小跳跃数是 2.(从索引 0 跳到 1 跳1步,然后跳3步到最后一个索引.)注意:假设你总是可以到达最后一个索引位置.详见:https://leetcode.com/problems/jump-game-ii/description/ Java实现: curReach是维护的当前能跳到的最大位置…

原题 题意: 是Jump Game的衍生题(题解),题意求跳到最后一格所需最少步数,(默认所测数据永远可以跳到最后一格). 思路: 利用贪心,遍历数组,记录在每一步可跳跃到的最大区域. 1.当前步数 超过已覆盖范围,则表示需要进行跳跃,同时更新已覆盖区域,可覆盖区域. 2.当前步数 在已覆盖范围内,说明无需进行跳跃,同时更新可覆盖区域. /** * @param {number[]} nums * @return {number} */ var jump = function (nums) {…
